Problems solved by technology

[0004] 1. Since the multi-point processing function is realized on the multi-point control unit in a centralized manner, the processing load of the multi-point control unit is heavy, especially when there are many system users and multiple meetings are held at the same time, the scale of the system is limited , unable to build a large multimedia conference system;
[0005] 2. During a multi-point conference, the images, sounds and data sent by all participating terminals are concentrated to the multi-point control unit, and the image and vo

Example Embodiment

[0021] Such as figure 2 As shown, the present invention consists of a tandem gatekeeper 101, multiple user gatekeepers 1021-102n (n greater than or equal to 2) cascaded, multiple multipoint control units MCU 1031-103n (n greater than or equal to 2) cascaded, multiple A multimedia conference terminal 1041-104n (n is greater than or equal to 2), the tandem gatekeeper 101 establishes a communication connection with each user gatekeeper 1021-102n, and coordinates the user gatekeeper 1021-102n to manage the entire system; at the same time, each user gatekeeper 1021-102n is responsible for managing the multimedia conference terminal 1041-104n and the multipoint control unit MCU 1031-103n under its jurisdiction, and establishes a two-way communication connection; each multimedia conference terminal 1041-104n is idle with the user gatekeeper 1021- 102n establishes a two-way communication connection. During the meeting, in addition to establishing a connection with the user gatekeeper 102...

Abstract

A distributed multimedia conference system based on IP network includes multimedia conference terminals, a multipoint control unit and gates characterizing that the said gates are divided into a junction gate and multiple user gates, each user gate is connected with its belonging multimedia conference terminals and the multipoint control unit, the junction gate is connected with and coordinates with each user gate to manage the entire system. Each of the multimedia conference terminal attending the meeting is connected with the multipoint control unit controlling the conference, having the control unit controlling the conference, having the control function only and the multipoint process function is separated from the multipoint control unit and realized at each multimedia conference terminal. This invention supports the multimedia conference function of image, phone and data to transmit the said signals to save network bandwidth by multicast.

Description

Technical field [0001] The invention relates to a multimedia conferencing system running in a network supporting IP services, in particular adopting distributed processing technology to realize a large-capacity multimedia conferencing system. It is also suitable for point-to-point systems, that is, systems for multimedia communication between two parties located in different places. Background technique [0002] The multimedia conference system connects multiple multimedia conference terminals located in different places through the communication network. Under the control of the multi-point control unit, the participants can communicate in multimedia ways such as images, voice and data. The multimedia conference system includes a multimedia conference terminal, a multi-point control unit (Multi-point Control Unit, MCU) and a gatekeeper (Gatekeeper, GK). The multimedia conference terminal conducts two-way communication with other terminals, multi-point control unit and gate...
